(ci. s4a1) 1 Claim.

This invention relates to new and vuseful improvements in apparatus' for drying hair, and is especially'designed as an improvement in the construction shown in my `cti-pending application for patent, filed April 13, 1940, Serial Number 329,545. l

One object of my present invention is'to provide the top of the head piece or' housing with aA moisture absorber made in sections that-may be easily and readily removed and replaced, as

may be required in the operation of the device. v

A further object of my presentinvention is to provide the respective sections of the moisture absorber with suitable recesses or openings to receive the insulating posts of` the main heating element and the fan shaft.

Still another object of my invention is toprovide the inlet ends or mouths of the air flow boxes or directors with supplementary heating elements to provide more uniform and effective air heating and` distribution.

Another object of my presentinvention is to insulate the down-take airpassage in such a way `as to prevent heat loss through the walls of the dryer into the room,

`Still yetanother object of my present inven tion is to `provide a head rest designed asrper-v manent equipment for my hair dryer.

With the foregoing and other objects in view that will appear as the nature of my invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated' in the accompany ing'drawings and more particularly pointed out in the appended claim.

In the accompanying drawings,` which are for illustrative purposes only and are therefore not drawn to scale:

Figure 1 is a vertical'longitudinal section of` the head piece or housing, `embodying my present improvements.

Figure 2 is a fragmentary side elevation of the upper end or top of the housing and asso.- ciated parts.

vFigure 3 is a horizontal section, taken on line 3-3 of Figure 1.

Figure 4 is a detail horizontal section, taken on line 44 o'fFigure 1.

Figure 5 is a bottom plan view absorber.

Figure 6 is a side elevation of the head piece of `the moisture Figure 8 is a face View of the form o-f head rest shown in Figures 6 and 7.

Figure 9 is an edge view and Figure 10'is a side elevation of the lower end of the housing, showing the use of another form of head rest.

Referring to the drawings for a more particular description of my invention, and in which drawings like parts are designated by like reference characters throughout the several views, the numeral I representstlie head piece or housing, ,4 2 a hollow semi-spherical perforated cap, which ts over the head and is situated at the lower. end of the central air intake passage or channel 3, and 4 `the air filter positioned in the air intake passage over the -aforesaid cap, A suction fan 5, carried by the lower end of the vertical shaft E, is disposed in the upper end of the air intake passage 3 above the air lter. The hous- `ing I is also formed with the annular down-take passage 1, terminating at its lower end in the circular rim 8, which extends around the head below the suction cap. A three speed motor 9 is mounted on top of the head piece or housing I.

or housing, illustrating the application of' one The rim 8 is provided with a plurality of adjustable air flow directors I0, preferably six in number, which direct the warm air to the head. All of the above features are shown in my co-pending application for patent heretofore mentioned andl form no part of my present invention.

My present invention comprehends a sectional moisture absorber II, in lieu of the lining I4,

.shown in my co-pendng application, which may be easily and readily removed and exchanged for a new element, as occasion may require. The moisture absorber II is preferably made in four corresponding sections II' formed in adjacent edges With the elongated registering slots or recesses I2 `to receive the insulating posts I3 of the main heating element I4 situated in the housing above the suction fan. The inner corners of the sections Il are recessed, as at I5, to form th central opening I 6 for the fan shaft 6. j In carrying ,out my present invention, I provide the supplementary heating elements I1, which are 'arranged adjacent the inlet ends or mouths I8 of the adjustable air flow directors, as shown. It has been found on experiment that only one and one-half inch ,of wire is required for each supplementaryheating element I1, and the use of the latter contribute to a more uni form andelfective heating of the air. In this y connection, it may be stated that the average 'hairu dryer requires approximately fty inches of wire heating element, whereas, in my device,

less than half that amount is required and more uniform and effective results obtained.

As a further improvement in my original dedown-take passage 1 with an outer lining or layer, as 20, of insulating material, to prevent heat loss through the wallsof the housing into the room. The heat out-put of hair dryers now in use is such that it is practically impossible to air condition beauty shops, but this objectionable feature is removed through the use of my device.

My improvements also comprise a head rest 2l, which is mounted at the rear side of the housing I, beneath the perforated cap 2, and is designed as a permanent feature of the device. In the form shown in Figures 6 to 9, inclusive, of the drawings, the head rest comprises the wire netting 22, supported by the frame 23, of strong wire, metal, wood, or other material; The device is held in place by the clamp 24, and may be adjusted in and out to suit the convenience of the patron, by means of the horizontal bar or arm 25 and set screw 26. My head rest permits the patron to relax and be perfectly comfortable while undergoing treatment.

In the modified form of my invention illustrated in Figure 10 of the drawings, the head rest isin the form of a strip of wire netting 21 attached at its ends, as at '28, to opposite sides of the cap and suspended like a hammock.

To facilitate the removal and exchange of the moisture absorber sections Il', the upper end of the housing is provided with the hinged doors 2|, held in closed position by the latches 30, or other equivalent means. The doors 29 may be swung in and out in a horizontal plane, as will be apparent.

u vice, I provide the inner wall I9 of the annular From the foregoing description taken in connection with the drawings, it is thought that the construction, operation and advantages of my present improvements will be readily understood without requiring a more extended explanation.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

An apparatus for drying hair, comprising spaced inner and outer walls connected together at their lower ends, said inner wall forming a central air passage, a cover for said inner and outer walls having a passage-way therein communicating with said central air passage andthe space between the inner and outer walls, a hollow perforated dome shaped member, mounted in the lower end of the central air passage and adapted to be placed over the head, a Ian mounted in the central air passage over the hoilow dome shaped member to draw the air up` wardly through the latter and cause the air to then flow downwardly through the space between the inner and outer walls, a heating elementdisposed above the fan, hollow circumferentially spaced adjustable air flow directors, extending through the lower end of the inner wall and dlrecting the ilow of the warm air inwardly toward the head, said air flow directors comprising inner and outer telescopic sections, one of said sections having peripheral openings communicating with the lower end of the central air passage below the perforated dome shaped-member, a sectional and removable moisture absorber mounted within the outer wall above said cover, and doors hinged to the outer wall above the cover, said doors adapted to swing open to permit the removal and exchange of the moisture absorber sections.
